FIELD: machine building.
SUBSTANCE: pipe connection consists of seat end with internal circular slot where into there is inserted flat end of second element of pipeline, of packing gasket and of lock member. The flat end and the seat end form a radial gap. The lock member consists of a tooth and a side adjacent to a wall when the gap is in the first range of gaps. When the gap is in the second range of gaps the lock member forms a turning point relative to the wall of the slot, while the tooth engages external surface of the second element of the pipeline because of lock member wedging.
EFFECT: increased reliability of connection.
